arch/Config.in.xtensa: provide BR2_ENDIAN symbol

Browse Source 
Packages get hints from the buildroot at configure time, e.g.
ac_cv_c_bigendian=yes/no. This particular hint is based on the value of
BR2_ENDIAN and when it doesn't match actual toolchain endiannes the
build may break.
Provide BR2_ENDIAN for xtensa to fix this sort of build errors.
